Which Drivers Are Supporting Growth Of The Oral Vaccine Market?

The oral vaccine market is projected to expand significantly due to the increasing incidence of infectious diseases. These illnesses stem from harmful microorganisms such as bacteria, viruses, fungi, or parasites and can be transmitted between individuals or through environmental factors. The rise in infectious diseases is largely attributed to heightened global travel, which facilitates the rapid cross-border movement of people and pathogens, thereby accelerating their worldwide spread. Oral vaccines are advantageous in addressing infectious diseases because they stimulate mucosal immunity within the gut, a critical entry point for many pathogens, offering effective protection at the site of infection. For example, in May 2025, the Health Security Agency, a UK-based government department, reported that England experienced an 11.0% increase in tuberculosis (TB) cases in 2023 compared to 2022. Thus, the growing prevalence of infectious diseases is a key factor driving the expansion of the oral vaccine market.
